Working Theory

The exhaust oxygen sensor – had been invented by Bosch - is a small sensor screwed into the motorcycle's exhaust system to measure the concentration of oxygen remaining in the exhaust gas to allow an Power Control Module to control the efficiency of the combustion process in the chambers. In modern bikes, these sensors are attached to the engine's exhaust pipe after the manifold to determine whether the mix of air and gasoline going into the cylinder is rich or lean. This information is sent to your Moto Morini Corsaro Avio's engine management, which adjusts the air fuel mixture to give the best possible fuel efficiency and lowest possible exhaust emissions.

Restore factory horses and optimum fuel efficiency as if your Moto Morini Corsaro Avio was new from factory.

Bosch patented ceramic technology affords best-in-class performance. The ceramic element is a critical part of the exhaust air fuel sensor. Bosch's patented materials and processes ensure unbeatable quality and engine performance. Also it sounds reassuringly, major motorcycle manufacturers place their trust in Bosch exhaust gas oxygen sensors. Why replace? Failure of these lambda probes, either through normal aging, the use of leaded fuels, or due to fuel contamination with eg. silicones or silicates, can lead to spoiled power capability and lower fuel efficiency.

Compatibility

Our Bosch motorcycle oxygen sensor is available to all bikes fitted with exhaust oxygen sensor, torqued in M18 x 1.5mm threaded nut. This lambda sensor will fit your Moto Morini Corsaro Avio if it is fitted with M18 lambda probe. This sensor doesn’t replace M12 sensors. Not quite sure this air fuel sensor fits your Moto Morini Corsaro Avio? Feel free to contact our Tech Support. Our trained Magnum product specialists are looking forward to respond to your inquiry. Heavy exhaust modifications trigger the ECU warning light. In this instance the replacement of the o2 sensor will not cure MIL issues. If so, you need to hook up oxygen sensor simulator to the exhaust o2 sensor(s)' harness in order to get rid of Electronic Control Unit limp mode causes the bike run inefficiently spoiling both power capability and economy.

Motorcycle Oxygen sensors are recommended to be replaced after each 30.000 miles - 48.000 km.

Good to know that Bosch invented the exhaust o2 sensor and it is first choice for lambda sensors throughout the world. An annual production of around 38 million lambda probes impressively demonstrates the high quality and experience delivered by Bosch. It therefore comes as no surprise that most Customers riding Moto Morini Corsaro Avio preferably choose a Bosch exhaust air fuel sensor when replacement interval passed.

All Bosch air fuel sensors come with special features. Double laser-welded stainless steel body protects the sensor against contamination. Pre-coated threads with anti-seize compound guarantees easy install and removal at any time. If original air fuel sensors are worn on your Moto Morini Corsaro Avio or give slow signal, you can save up to 10% a year in gasoline costs! Check your lambda probe frequently on your Moto Morini Corsaro Avio and replace them with every second tune-up to improve motorcycle horses and reduce harmful exhaust emissions.

1 x Installation Instructions

Oxygen sensors are used to reduce vehicle emissions, by ensuring that engines burn their fuel efficiently and cleanly. Robert Bosch GmbH introduced the first automotive lambda probe in 1976. The sensors were introduced in the US from about 1980, and were required on all models of cars in many countries in Europe in 1993. By measuring the proportion of oxygen in the remaining exhaust gas, and by knowing the volume and temperature of the air entering the cylinders amongst other things, an ECU can use look-up tables to determine the amount of fuel required to burn at the stoichiometric ratio (14.7:1 air:fuel by mass for gasoline) to ensure complete combustion. When an internal combustion engine is under high load (such as when using wide-open throttle) the oxygen sensor no longer operates, and the engine automatically enriches the mixture to both increase power and protect the engine.

Internal Design

The sensor element is a ceramic cylinder plated inside and out with porous platinum electrodes; the whole assembly is protected by a metal gauze. It operates by measuring the difference in oxygen between the exhaust gas and the external air, and generates a voltage or changes its resistance depending on the difference between the two. The sensors only work effectively when heated to approximately 300°C, so most lambda probes have heating elements encased in the ceramic to bring the ceramic tip up to temperature quickly when the exhaust is cold. The probe typically has four wires attached to it: two for the lambda output, and two for the heater power.

Operation of the Zirconia O2 Sensor

The zirconium dioxide, or zirconia, lambda sensor is based on a solid-state electrochemical fuel cell called the Nernst cell. Its two electrodes provide an output voltage corresponding to the quantity of oxygen in the exhaust relative to that in the atmosphere. An output voltage of 0.2 V (200 mV) DC represents a lean mixture. That is one where the amount of oxygen entering the cylinder is sufficient to fully oxidize the carbon monoxide (CO), produced in burning the air and fuel, into carbon dioxide (CO2). A reading of 0.8 V (800 mV) DC represents a rich mixture, one which is high in unburned fuel and low in remaining oxygen. The ideal point is 0.45 V (450 mV) DC; this is where the quantities of air and fuel are in the optimum ratio, called the stoichiometric point, and the exhaust output will mainly consist of fully oxidized CO2. The voltage produced by the sensor is so nonlinear with respect to oxygen concentration that it is impractical for the electronic control unit (ECU) to measure intermediate values - it merely registers "lean" or "rich", and adjusts the fuel/air mixture to keep the output of the sensor alternating equally between these two values. This type of sensor is called 'narrow band', referring to the narrow range of fuel/air ratios to which the sensor responds. The main disadvantage of narrow band sensors is their slow response: the control unit determines the exhaust gas composition by averaging the high and low swings in the sensor's output, and this process creates an inevitable delay Not quite sure this oxygen sensor fits your motorcycle?

exactly the same as what I removed

Bosch is one of the OE suppliers for BMW bike O2 sensors. This o2 sensor is exactly the same as what I removed from my K1200R, except that it didn't have the BMW logo didn’t have to OE connector and the price that goes along with that. Easy to remove and replace about 20 minutes. This was installed on a 2008 BMW K1200R. Would buy again. Awesome customer support when you are in need of.

totally satisfied

After my old o2 sensor failed in my Griso I bought two of these puppies at a price that other web sites charge for 1. 3-day delivery for free. Within an hour of receiving them my bike was back in action. I am totally satisfied and happy customer. Bosch and magnum a good combination.

This bosch o2 sensor fits like factory in my 1190. Works well for the fracture of the price. Although you need to crimp the connectors, it's a piece of cake, harness length is the same as original. What more could you want out of an o2 sensor?

throttle response from the engine was noticeably better

Finally got to ride my bike with the new oxygen sensors fitted. Didn't seem to make much difference at first but after a while the throttle response from the engine was noticeably better. Great deal for the price. As good as any direct fit OEM, but for lot less.
